Actually, the article is not "comprehensive"; it's what we could put into it without going too grossly over the CACM word count limit for major articles. The full paper we're still working on, and major topics had to be cut out, unfortunately, along with lots of detail.
The ACM queue posting is that of the CACM article that will appear in the "dead tree" magazine next month, along with an interview of Van Jacobson, myself, and Nick Weaver done by Vint Cerf. I hope the full paper will be available by then. The cutting room floor is very littered. We have to pick up those pieces and pull it back together again.
